I can help with this, I will build your karaoke app in Kotlin with Material 3 — track catalog with search, synced lyric scrolling over instrumental playback, audio/video recording with local save and share, and a pitch-based scoring screen. For audio latency, I will use Oboe (the native C++ audio library) to handle mic input alongside MediaPlayer for the instrumental track. This keeps capture latency under 20ms on most devices, which is critical for accurate pitch scoring. Without Oboe, standard MediaRecorder introduces enough delay that scores become unreliable — especially on budget hardware like the A32. The song manifest will be a simple JSON file so adding tracks means dropping an instrumental, a timed-lyric JSON, and updating one entry. Looking forward to talking through the details. Kamran

I have engineered several audio-focused Android apps where precision timing and low-latency feedback were the primary KPIs. Having integrated the Oboe library for real-time signal processing, I understand that a premium karaoke experience relies on perfect synchronization between vocal input and the instrumental track. My approach bridges high-level UI responsiveness with the native audio layer to ensure a professional-grade performance that feels intuitive and lag-free for the end-user. I will implement a custom media engine leveraging ExoPlayer for playback and a dedicated PCM-based recording buffer for capturing high-fidelity vocals. I'll utilize a custom Lyrics Engine that parses LRC formats to drive a frame-accurate UI overlay, ensuring text highlights in sync with audio timestamps. For the final export, I’ll integrate an FFmpeg pipeline to mix audio streams, allowing for real-time effects like reverb or gain normalization before saving to the MediaStore. The app will be built in Kotlin using Clean Architecture, with Room for offline persistence and WorkManager for background rendering. Regarding the content source, are you planning to integrate a third-party API or will the app rely on a proprietary library of tracks? Do you have specific preferences for audio effects like pitch correction, as this requires specific DSP considerations? I am ready to dive into the technical specifics or jump on a brief call to finalize the development roadmap—feel free to reach out to discuss how we can bring this project to life.

@rogelitoc

Hello, In my opinion, the problem of this project is that achieving smooth audio-visual playback with real-time lyric synchronization is technically demanding, especially across different Android devices. I will use a modular architecture to manage the catalog and playback features efficiently. The app will leverage Kotlin Coroutines for asynchronous operations, ensuring responsive UI during playback. I will implement a local database for song metadata, allowing seamless integration of new tracks via JSON, while ensuring consistency in audio and video recording functionalities. Edge cases around audio latency will be addressed using proper buffering techniques. The deliverables will include a Play-store-ready APK, a signed AAB, well-structured source code in a private Git repository, a README for song integration, and a test video demonstrating the scoring feature. My experience includes developing audio-centric applications, ensuring low latency and high performance. I can start immediately. Regards.
